Our three year old cheap gps device has started totally malfunctioning--reverts mid-trip to previous destinations with no warning! Should we get a Garmin or an app for our iPhones (we both have 4s) or something else? We would like something that gives voice directions while driving and shows where we are on a map during the trip. Don't want to spend a ton but would like something that actually works properly.
Thank you!
